Letters Patent No. 85,928, dated .Hmmm-y 19, 1869. l

rMPR'ovnMnNT IN PEN-HOLDERS.

' The Schedule referred to :ln these Letters Patent and making part ofthe same.

To all lwhom it 'may concern Be it known that I, DAVID E. HALL, ofDetroit, in the county of \Vayne, and State of Michigan, have inventedcertain' new and useful Improvements in Spring Pen-Holders; and I dohereby declare that the following is a full and complete description ofthe saine, reference being had to the accompanying drawings, inakingpart of this specifica-tion, in which- Figure l is a view of the pen andholder.

Figure 2, a viewI of the pen and section of clamp.

Figure 3, a view or" the opposite side oi' fig. 2.,`

Figure 4, a view of the two sections of the clamp and pen.

Like letters of reference refer to like parts in the different views. Y

` A, tig. 2, represents a metallic plate, 011e end of which is providedwith ears or wings, B, which are folded over. and down upon the face ofthe plate, under which the stem of the pen C is inserted, as representedin iigs. 2 and 4.

D, Figure 5, is a supplementary plate, which, as will be seen, issomewhat narrower than the plate H, and upon which it lies with one endinserted under the ears, and resting upon the pen, serving as a wedgewhereby the pen is clamped rmly and securely to the plates.

It will be observed that the edges of the pen fit closely up in theangle o'f the ears, but that the edges of the supplementary plate donot, it being made to occupy the central part of the plate, so that thepressure of the fastening is upon the central part of the pen thereforeno expansive pressure is exerted upon the sides; hence there will be notendency to change the curve of the pen, and so distend the slit orotherwise injure the point. 5

The manner of securing these plates or clamps to the handle is "asfollows, viz: In the end of the handle E,

,enclosed by the ferrule F, is cut a deep slit, in which are insertedthe two plates, on holders, as they lie upon each other, as shown iniig. 4.

When thus inserted, the barbs or nibs ,struck up in each plate, preventthe holder from being pulled out, unless the slit is dstended for thatpurpose.

rIhe ferrule is then slipped on, which compresses the slit end of thehandle upon the plates and barbs, thereby holding the pen neatly andrmly in the handle.

It will be observed that the holder and pen thus attached to the handledo not touch the ferrule at any point, andare in no way connected toit,`but simply pass through from the end of the handle out; hence thespring given "to the holder is not restrained by it, but acts freely andwith its full strength, which will be of greater or less tension,according to the length of the holder,` the length being more or less,or in proportion to the depth it may be inserted in the slot of thehandle.

The peculiar advantage resulting from the use of a pen thus connected t6the handle is, that a greater degree of springiness is obtained to thepen than if the same were attached to the holder without a spring, inthe ordinary way;hence it will write with a lighter hand and with lessstrain upon the fingers; the heavy and lighter strokes can be moreevenly given, and withl greater certainty, so that the penman is enabledto execute his work with greater ease and elegance.

What I claim as my improvement, and desire to secure by Letters Patent,is

The metallic plate A, ears B, and supplementary plate D, as constructedand arranged, in combination with the pen G and handle E, for thepurpose specified.
